HEADLIGHTQOPERATENG MECHANISM...

Specification of Letters ?atent.

Patented Feb. 12, 1907.

Application filedliovembei 7.190s. Seria No. f. .2344.

.FrankliJn-in the county of Norfolk and fitate of Massachusetts, have invented new anduseful Improvements in Headlight-OperatngMechanism, of which the following-is a specification.

My invention pertains to headlightf-operatmg mechamsm for cars, and it contemplates the provision of a simple and durable mechanism for turning a headlight synchronously with the swinging of the pivoted truck of'a car, as when the car is turning a corner,

so as to direct the beam of light from the headhght in the direction the car is to take subsequent to making the turn.

The invention will be this specification, in whichethe' accompanying drawings, forming part of Similar letters designate corresponding arts in all of the views of thedrawings, re-

. terring to which.

A is the body of a motor-car, and B is a truck ivotally connected with the body in theor inary well-known manner with a view of better adapting-the car to pass around curves;

- On the dash d of the body'A are forwardly extending bearings 'b, and in these bearings lar c, and in that-way fixed on is journaled a vertical rock-shaft C, having at c a collar which bears on the upper bearing b,

and in that way holds the shaft against downward movement. The said shaft 1S equipped with a headlight-carrier .D, which is preferably of angular form, as shown, andis provided on the rear side of its upright portion with a sleeve e, which is clamped between a nut fand'the before-mentioned colthe shaft C so as .to turn therewith. At a point adj acent to its lower end and in a plane below the under;

side of the car-body A the shaft 0 is provided.

with a crank-arm g, from the outer portion of which depends abolt h, carrying an antifricfully understood. from the following description and claim when the same are read in connection with Figure 1- is a side elevation of one end portion'roller7c, Fig. 2, for a purpose presently set forth.

E is an upright bolt fixedly connected 'to' and TlSlIlg from the forward portion-of the truck B."

F is a standard-brace fixedon the upper side of the truck and receiving the upper portion of the bolt E. r

G is an antifriction-roller, which is loosely mounted on thebolt E and bears on the standard-brace F and is retained on'the bolt through the medium of a nut l and a washer II is a bolt fixed to and depending from the car-body A at a pointin'advance of the truck B. I is a depending brace fixed to the carbody A and receiving said bolt H. I

J is an antifriction-roller held on the bolt H below the brace 1, preferably through the medium of a nut p and a washer r, and M is a horizontally-swinging lever havingan aperture 8, receiving the antifriction-roller J, whereby the lever is fulcrumed on the bolt H. In its forward arm the said lever M is providedwvith a longitudinal slot 75, which receives the antifriction-roller k on the crankarm 9 of the shaft C,and in its rear arm the lever has a longitudinal slot u,inwhich is dis-- posed the antifriction-roller G on the bolt In virtue of the construction described in the foregoingit will be seen that incident to the turning of the truck B on its pivot, as when the car is passing around a curve, the

v lever .M will be swung horizontally and its forward'arm thrown in a direction opposite to that in which the truck turns. The crankarm 9 of the upright shaft C will obviously be caused to move with the forward arm of the lever M, and this will result in the shaft C andthe headlight-carrier D being turned in the same direction as the truck, so as to enable the beam of light from the headlight to indicatethe direction the car is to take subse- .quent to passing around the curve. From this it follows that as the forward portion of the car takes a curve to pass'from one street to astree't disposed at a ri ht angle thereto theibeam of light from the eadlight will be v directed up the street into which t ecar is tov pass, with the result: that persons on said street will'be warned of the approach of .the car.

It will beathered from the foregoing that may improve mechanism is advantageous because .a single lever transmits motlonfrom the truck to the vertical shaft on which the ment of my invention; but I desire it.under-' stood that in practice various changes in the form, construction, and relative arrangement of parts may be made Within the scope oi the appended claim without involving departure from my invention.

Having describedmy invention, What I claim, and; desire to secure by Letters Patent, isv The combination in a headligheoperating seense mechanism, of a car-body, a horizontally-- swinging truck pivotally connected therewith and carrying a bolt on which is an antifriction-roller, a vcfrticel rock-shaft journals-d in a bearing, on the body and equipped" with a headlight carrier, .a cranlearin fixed on the lower portion of the rocleshaft and, carrying a bolt on which is an antifriction-roller, and a horizont'allyswinging lever fulcruined on the car-body and having a longitudinal slot in its forward arm receiving the antifrictionroller on the bolt of the crank-arm and also having a longitudinal slotiin its rear arm re ceiving the antifriction-roller of the bolt on the truck.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
